vTo all whom t may concer/n:

Be it known that I, WILBUI; L.l WRIGHT, a

citizen of the United States of America, and

This invention relates to certain improve-l ments in ice cream packages; and the objects and' nature of the invention will be readily understood by those skilled in the 'art in the light -of the follqwing explanationV of the accompanying drawings illustrating what I now believe to be the preferred mechanical expression or embodiment of my invention from among other forms, constructions and arrangements within the spirit and scope thereof. n

lt is an object of my invention tosprovide rectangular paper containers for ice cream, .that can be knocked down or folded 4flat into small compass for convenient and economical packing, shipment, and storage; that can be readily assembled and set up for use; that can be quickly andeasily filled-by the use of the ice cream cylindrical container filling machines now on the market by sub stituting filling nozzles rectangular in cross section for the cylindrical 'filling nozzles now employed in such machines; and that will serve to protect and insulate the contained hardened ice cream and will reduce to the minimum possibility of outside air leaking into the package.

With these and other objects in view my invention consists in certain novel features in construction and in formations and arrangements as more fully and particularly set forth and specified hereinafter.

Referring tothe accompanying drawings: Fig. 1 is a perspective view of the container, the parts thereof 'assembled and brought to form and condition for application to the filling nozzle of the ice cream container filling machine, a lower corner of the container being broken away;

In the drawings l s ow ordinary folding pape 'box of commerce being collapsed into flat form for convenient and economical storage and packing (Fig. These folding boxes are usually composed of va single flat paper blank hav- -ing its ends secured together to form the the blank having parallel score lines defining thekside faces of the body so that the body can fold or collapse (Fig. 5,) With two side walls superimposed on and parallel with the other two side walls, and so that the body can be expanded or distended to operative shape forming the oblong bodyl rectangular in cross section. ln the particular. example illustrated, each end of the collapsible body any suitable or Vl is formed with a pair of short opposite to lie across the end opening and then folding the closing l iap 3 so as to loosely overlie the flaps 2.

rlhe long outer flap 3 is then secured by tucking its projecting end 3x into the box end between the side edges of flaps 2 and the inner surface of the box body. The opposite end 'of the box is then closed in like manner.

The blank is usually scored versely of the various ing lines.

Folding or collapsible paper boxes of various constructions are more or less standard on the market at a comparatively low cost, and are Well adapted to receive display and advertising matter, and :is each box'can be collapsed to vflat form such boxes can be packed in large quantities in small space and are economical for storage and shipment.

However, no matter how desirable such paper boxes may be from economical and advertising standpoints, they are not per se on lines .trans-- iiaps to provide foldcontainers for ice cream, i. e., to receive the tan semi-frozen ice cream. as it flows from the freezer, preparatol 'I to hardenin and storing in' the har ening room, an final delivery to the ultimate consumer in the hardened State inthe original containers.

In the first place, these folding paper boxes are not even approximately air and liquid tight and the semi-frozen cream as it Hows from the freezer would ooze through the end closures of the boxes before the cream became thoroughly hardened in the hardening room and the package would thereby become ineffective and unsalable for various reasons, particularly on exposure to the atmosphere.

In the second place, such open-end folding boxes cannotbe properly filled by the use of ice cre-am container filling machines, particularly to form blocks of layer ice cream. I have solved this problem by providing a paper container for ice cream, rectanguluar in cross section. and embodying a foldable paper box (for instance such as hereinbefore described) that can be filled by ice cream container filling machines, and that will successfully hold the cream through the process of hardening and protect, insulate and preserve the hardened ice cream through the subsequent steps of storing, transportation and final delivery to the ult-imate consumer. lheconditians require that the oblong rectangular container be filled through one end and that the container rovide approximately fiuid and air tlght Walls, walls of sufiicient stiffness and stability to stand up under the filling operation and to cooperate with the filling nozzle during that operation to exert suction pull, if need be, on the cream in the nozzle to accelerate the filling operation; and also that the open end of the-box be closed approximately air and fluid ti ht after the filling operation.

I` meet these conditions by combining. a peculiar inner icecream-receiving recepta-- cle or container, with the folding. collapsible rectangular open-end paper box which constitutes-an outer enclosure for the inner container. This inner container is composed of. a tubular body more or less snugly fitting the longitudinal ing 4 paper box and in length interior length of the paper closuresfor the opposite open ends of said inner tubular body.

The'inner tubular body is, in the example illustrated, composedof an imperforate rec- `ar blank or sheet 8 of comparatively sti paper material, so called paper board` preferably treated with parafline or other- Wise rendered moisture proof. This sheet is formed with score lines, or is otherwiseformed to fold on the parallel transverse lines 8 to` form an oblong body rectangular exceeding the in cross section. The ends of the blank overinner surfaces ofV the foldf box, and end lap at 8a, and these ends can be secured together before the'. body is inserted' in the lpaper box or can be left disconnected so inner bodies. as for this purpose I preferably employ fiat rectangular water-proofed paper caps or disks 10 composed usually of the same kind or grade of paper material as the blanks 8, although if-so desired, the end closure for the inner b'ody can be fiange'l to slip either within or at the exterior of the inner body ends.

The boxes and blanks are stored by the ice cream manufacturer in flat form. and are set up and assembled approximately as needed for filling.

- In assembling, the paper box is folded to operative form and the lower end thereof is closed by the flaps 2. 3, .as hereinbetore described, before or after the bottom closure` disk 10 is located in the lower end of the box fitting closely down on the box closure fiaps 2, 3. The end disks l0 closely conform to the interior cross sectional dimensions of the box, in fact the disks l0 are usually slightly oversize with respect to s'aid internal box dimensions. In assembling, it is hence necessary to exert pressure in forcingthe stiff lower disk' 10 into the lower end of the box to position squarely across the box end and against and parallel with the flap closure. The edges of the stift disk 10 thus preferably press tightly against the inner surfaces of the box and approximately seal the lower end of the box'. This stiff botto-m disk l0 when thus positioned in the lower end of the box serves to hold the box in set up form and against collapse.

The body 8 is then brought to-set up form and inserted longitudinally into the box through the upper open end of the box.

This body is expanded to snugly fit Within 'the paper box and is pressed down on the bottom disk l0 so that the lower end edge of the body snugly abuts the edge portions of the'top face of the disk. The inner body 8 in length exceeds the internal length of the paper box and hence projects a short distance above the upper open end of the paper box. The comparatively stiff material of the inner body 8 holds the paper box to form and against collapse. The container is new ready for filling, and can be filled by an ice cream container filling machine equipped with a rectangular nozzle instead of the cylindrical nozzle now employedin such machine. These machines are' now em loyed for filling cylindrical paper cans. t. uch a machine now embodies a depending c lindrical nozzle open at the lower end an internally divided to provide longitudinal passages receiving flowable ice cream from different elevated supplies. Usually the different supplies contain ice cream of di'erent flavors so that columns of differently flavored cream will be simultaneously delivered from the lower end of the nozzle into the container being filled. In the machine as now used, the cylindrical paper can is placed on they lower end of the nozzle and moved up on the exterior thereof with the can more or less snugly fitting on the nozzle. The can is filled from the bottom up as itis with- Y. drawn from the nozzle, more or less suction pull, if desired, being thereby exerted on the cream in the nozzle to accelerate its flow into the can. The filled can is then moved horizontally across the lower end ofthe nozzle to separate the cream inthe can from the nozzle. Usually an exterior head snugly tits the nozzle and reciprocates vertically thereon and receives and forms a tight fit' with the to edge of the can and moves with the can during its vertical movements on the nozzle.

The rectangular paper containerof my present invention is designed and adapted to cooperate with the nozzle and head (when changed to receive the container of rectangular form) as does the cylindrical can in the machine just described. l

The projecting upper end of the inner body of the container is 'arranged to t and form a more or less tight joint with the head that slides on the exterior of the nozzle and the interior of said body is arranged to more or less snugly t the exterior of the nozzle.

The inner body and the bottom disk render the container sufficiently air tight to create suction pull on the. cream in the nozzle, if that be desired, when the container is rapidly drawn down on the nozzle. ln fact, the inner body, renders the container of the desired stidness and stability to cooperate with the filling machineduring the filling operation. The flaps 2, 3, at .the upper end of the container are swung down on their normal fold lines 2', 3', so as to be free of the projecting upper end of the body and expose the same to fit in the exterior head on the nozzle, during the filling operation.

When the container has been filled with the'semi-frozenv cream, and withdrawn frpm the machine, the top closure for the inner,

\ body, whether the flat paper disk l0 or a flanged paper disk, is placed over the open top of said body to rest von thetop edge thereof and close the same, the same as the lower end of said body iis closed. The top closure is then retained in place by closing the upper end of vthe paper box through the medium of its top flaps 2, 3, the same as the lower end of said box is closed by the corresponding-lower end flaps. There is this diderence, however, owing to the projected upper end of the innerbody, namely, the top flaps 2, 3, extend vertically from the top edge of the outer box, and then extend inwardly and horizontally across the top face of the top disk l0, consequently the upper end flaps of the outer paper box, are formed with the additional fold or bending lines 2a, 3a, where said flaps bend to pass in on top of the top closure 10.

c When the package of ice cream is thus sealed, the engagement between the edges of the body 8 and the end closures 10 and between the overlapping portions 8al of the body, are sufficiently tight to prevent objectionable leakage of cream at such joints before the cream is subjected to the freezing process in the hardening room.

When the packages are placed in the hardening room, the vapor from the semifrczen cream will be frozen in and around said joints between meeting paper edges and faces and within-the paper boxes and will thereby tightly seal such packages so that the paper containers will effectively protect the cream and permit deliverythereof at homes of consumers in the originalpackage, gaining with the rectangular container, approximately the advantages and utility attained bythe use of cylindrical paper cans of proper construction, with` the added advantage gained by containers that can be,v packed flat and in cheap outside boxes that can be cheaply supplied With advertising and display matter.

It is evident that various changes, modications and variations might be resorted to without departing from the spirit and scope of my invention and hence I `do not wish to limit myself to the exact disclosures hereof.
